Public Function Contains (index As Object) As Boolean

Paramètres

Retours

Valeur booléenne qui indique si la collection est accessible par nom, identité ou index. La valeur true indique que la collection est accessible à l’aide de la syntaxe DtsProperties[index]. La valeur false indique que l’indexation ne peut pas être utilisée pour récupérer des éléments de la DtsProperties collection.

Exemples

L’exemple de code suivant utilise la Contains méthode pour voir si l’une des propriétés de la collection est «CertificateObject ».

using System;  
using System.Collections.Generic;  
using System.Text;  
using Microsoft.SqlServer.Dts.Runtime;  

namespace DtsProperties_API  
{  
    class Program  
    {  
        static void Main(string[] args)  
        {  
            Package pkg = new Package();  

            // Get the Properties collection from the package.  
            // This shows the default properties set on new packages.  
            DtsProperties pkgProperties = pkg.Properties;  

           // Create the enumerator.  
            PropertyEnumerator myEnumerator = pkgProperties.GetEnumerator();  

            // Show the use of the Contains method.  
            Boolean containsCertObj = pkgProperties.Contains("CertificateObject");  
            Console.WriteLine("Contains CertificateObject? {0}", containsCertObj);  

            // Show the use of the item[x] syntax.  
            String aName = pkgProperties[5].Name;  
            Console.WriteLine("Property 5 is {0}", aName);  

            // Show the use of the MoveNext and Current methods.  
            int i = 0;  
            while ((myEnumerator.MoveNext()) && (myEnumerator.Current != null))  
            {  
                Console.WriteLine("[{0}] {1}", i++, myEnumerator.Current.Name);  
            }  
        }  
    }  
}
